docs: def getFirstNetworkView(self, networkId, file, verbose=None):
          """
          This returns the first view of the network. Cytoscape can have multiple views per network model, but this feature is not exposed in the Cytoscape GUI. GUI access is limited to the first available view only.
          
          If the `file` parameter is left unspecified, the response will contain data in [Cytoscape.js](http://manual.cytoscape.org/en/stable/Supported_Network_File_Formats.html#cytoscape-js-json) format.
          
          If the `file` parameter is specified, the Network View will be written to a file, and the response will contain the location of the file in the following format:
          
          ```
          
          {
          "file": "/media/HD1/myFiles/networkView.sif"
          }
          ```
          
          The format of the output file is defined by the extension of the `file` parameter.
  
          :param networkId: SUID of the Network
          :param file: A path to a file relative to the current directory. The format of the file written is defined by the file extension.
